Product Details
1. Basic Information
- Product Name: Defoamer
- Brand Model: VORANOL 3010
- Packaging Specification: 210 kg/barrel
- Main Ingredient: Polyether polyol (a polymer compound polymerized from propylene oxide and ethylene oxide as main raw materials under the action of catalysts)
2. Product Characteristics
(1) Physical Properties
- Appearance: Colorless to light yellow transparent viscous liquid with good fluidity at room temperature, convenient for industrial batch addition.
- Hydroxyl Value: Approximately 30 mgKOH/g. The hydroxyl content in the molecular structure is moderate, and the reactivity with raw materials such as polyisocyanate is stable.
- Viscosity: About 1000 - 1500 mPa·s at 25°C, suitable for uniform dispersion in sponge foaming and detergent systems.
- Water Solubility: Easily soluble in water and most polar solvents, with excellent compatibility with water - based detergents and foaming agents.
(2) Core Performance
- Low Foam and Foam Inhibition Characteristics: In the production of soft block sponges, it can inhibit excessive foam generated by mechanical stirring and gas injection during the foaming process to ensure uniform distribution of cell holes; when used in detergents, it can reduce the foam height of surfactants during the washing process, especially suitable for low - foam scenarios such as high - pressure spraying and machine washing.
- Chemical Stability: Resistant to acids, alkalis and electrolytes, stable in performance within the pH range (5 - 10) of detergents, and does not have side reactions with washing components; in sponge foaming, it has strong anti - aging properties and does not affect the physical and mechanical properties (such as resilience and compressive strength) of foam products.
- Environmental Friendliness: The raw materials do not contain harmful substances such as APEO, which meets the requirements of the EU REACH regulations and is suitable for environmentally friendly detergents and sponge products for food contact.
3. Action Principle
- Sponge Foaming Scenario: Polyether polyol regulates the surface tension of the foaming system to promote uniform generation of bubble nuclei, and at the same time inhibits excessive fusion and rupture of bubbles to form a fine and uniform cell structure; its hydroxyl groups react with isocyanate to form a polyurethane network, enhancing the strength of the foam skeleton and preventing collapse.
- Detergent Scenario: The polyether segments in the molecule unfold in water and adsorb on the surface of the bubble liquid film, reducing the film elasticity and destroying the stability of the bubbles; at the same time, it prevents the aggregation of bubbles through the steric hindrance effect to achieve a low - foam washing effect.
4. Applicable Scenarios
(1) Production of Soft Block Sponges
- Furniture Sponges: Used for foaming of sofa and mattress sponges to control the foam rising rate, avoid phenomena such as "heart - burning" and "collapse", and improve the density uniformity and hand feel comfort of the sponge.
- Packaging Sponges: In the production of sponges for packaging electronic products and precision instruments, ensure that the cell holes are fine to enhance the cushioning and shock - absorbing performance, and at the same time reduce the rejection rate caused by uneven foam.
(2) Low - Foam Detergents
- Industrial Cleaners: When cleaning metal parts and automobile parts by high - pressure spraying, inhibit the generation of foam to avoid clogging of nozzles or affecting the efficiency of ultrasonic cleaning.
- Machine - Wash Detergents: Added to special laundry detergents for washing machines and dishwashing detergents to prevent foam overflow from affecting equipment operation, and at the same time improve the stain removal ability (detergents are easier to penetrate fabric fibers in a low - foam state).
- Food - Grade Detergents: Complies with FDA certification and is used for cleaning food processing equipment. The low - foam characteristic facilitates rinsing and reduces the risk of chemical residues.
5. Usage Methods and Precautions
(1) Usage Methods
- Addition in Sponge Foaming: Add 0.5% - 1.5% based on the total amount of polyols. After mixing with catalysts, foaming agents and other raw materials, add them to the reaction system. It is recommended that the temperature be controlled at 20 - 30°C and the stirring speed be 800 - 1200 rpm.
- Addition in Detergents: Generally, the addition amount is 0.2% - 0.8% of the total formula amount. Add it in the compounding stage, stir to dissolve and then can be filled directly; in high - pressure cleaning scenarios, it can be appropriately increased to 1% to ensure the low - foam effect.
(2) Precautions
- Storage Conditions: Store in a sealed manner in a cool and dry place, avoid direct sunlight, store at a temperature of 5 - 35°C, and prevent the viscosity from increasing due to long - term high temperature; after opening, it needs to be protected with nitrogen to avoid moisture absorption or oxidation.
- Safety Protection: Wear rubber gloves during operation to avoid direct contact with the skin (some people may be allergic); if it comes into contact with the eyes, rinse immediately with plenty of water and seek medical attention.
- Compatibility Taboo: Avoid direct mixing with strong oxidants, strong acids and strong alkalis. Compatibility tests (such as foam height test, stability test) should be done before use in new formulas.
